Studying integrated science for junior high starts with one realization: physics, chemistry, biology, and earth science are taught as one connected subject. Grasp the core concepts through themes, link the branches together, then confirm them with simple observation. This way, the material from grade 7 to grade 9 feels orderly and makes sense.
- Integrated science unites four branches within a single subject
- Understand concepts first, and technical terms follow naturally
- Themes become the bridge between physics, chemistry, and biology
- Junior high integrated science books for grades 7, 8, and 9
- A blank notebook for cross-branch concept maps
- Simple observation materials found at home
What is integrated science at the junior high level
Integrated science is how Kurikulum Merdeka arranges science at junior high into one whole subject. Throughout phase D, meaning grades 7 to 9, students learn physics, chemistry, biology, and earth science under the same umbrella. The four branches are organized to speak to one another, so students grow used to viewing natural phenomena from several angles at once. This arrangement has a clear reason. Everyday events rarely sit within a single branch of science. Boiling water involves energy (physics), a change in the state of matter (chemistry), and the water cycle that touches biology and earth science. When material is presented in an integrated way, students practice connecting cause and effect across branches. Understanding how to study integrated science for junior high means building the habit of thinking holistically from the start, so the chapters that come later feel connected to one another.
Four branches united in junior high science
Physics
Motion, force, energy, heat and temperature, vibration, sound, light, and simple electricity. Junior high physics emphasizes observing phenomena and simple measurement, with formulas kept light.
Chemistry
Properties and states of matter, elements and compounds, mixtures, physical and chemical change, and acids and bases. The focus is recognizing everyday materials and how they change.
Biology
Classification of living things, cells, human organ systems, ecosystems, and heredity. Biology invites students to observe life from the smallest units to the connections within an environment.
Earth and space
Earth layers, the solar system, weather and climate, and natural cycles. This branch links physical and chemical phenomena to a wider scale across the planet and sky.

Six steps to study integrated science for junior high
The sequence below helps students organize integrated science from the big picture down to practice questions. Each step can be repeated for every new chapter throughout the school year.
- 1
Read the big picture of each semester first
Before starting the first chapter, open the table of contents of the integrated science book and observe the flow of a full semester. Group the chapters by their branch, then mark which chapters relate to one another. In grade 7, for example, the material on matter and its changes touches the material on heat and temperature. By seeing the big picture first, students have a sense of where the lessons will flow, so every new chapter feels like it has a clear place. This step also helps parents guide, since they know which topic is running and what comes next.
Tips- Write a full semester of chapter titles on one page so they can be seen together
- Use different colors for physics, chemistry, biology, and earth science topics

Understand core concepts before memorizing terms
Integrated science is full of terms, from photosynthesis to conduction. Memorizing a list of terms without understanding their meaning makes material fade quickly. Start with simple questions: what is actually happening, and why. Once a student understands that photosynthesis is how plants turn light into food, the technical terms around it become easy to remember. Indonesia's science literacy score, still below the OECD average, shows that concept understanding needs to come first. Ask your child to re-explain one concept in their own words. If they can tell the story without reading the book, the concept is truly understood.
Tips- Ask your child to explain a concept as if teaching a younger sibling
- Use examples from the kitchen, the yard, or the trip to school
Piling up term memorization right before a test without understanding the concept makes material easy to mix up and quick to forget. - 3
Connect the branches through themes
The heart of studying integrated science for junior high lies in the habit of connecting. Choose one theme, then trace its trail across several branches. The theme of water, for instance, touches changes of state (chemistry), heat and energy (physics), the water cycle (earth science), and the role of water for living things (biology). When students grow used to linking themes this way, material that seems scattered comes together into one whole story. Build the habit of asking which other branch also plays a part in this phenomenon. This holistic way of thinking is the true aim of the integrated science curriculum.
Tips- Draw a simple diagram with one theme in the center and branches around it
- Pick themes close to daily life: food, weather, the body, or vehicles

Confirm it through simple observation at home
Science comes alive when students see the evidence for themselves. Many junior high science concepts can be observed with materials found at home. Placing ice cubes in two different spots shows how temperature affects melting speed. Planting bean seeds on damp cotton shows the stages of germination. Direct observation turns abstract theory into an experience remembered for a long time. Ask your child to note what they observe, predict the result first, then compare it with reality. This habit of predicting and checking is the core of the process skills required by the phase D learning outcomes.
Tips- Always write down the predicted result before the observation begins
- One small observation per chapter is enough, as long as it is regular
Make sure observations are safe. Avoid materials that are excessively hot, sharp, or strong-smelling without an adult present. - 5
Organize with concept maps and term cards
After understanding and observing, students need to tidy their knowledge so it is easy to recall. A concept map links the big idea with the branches that explain it on a single page. Term cards help recall technical vocabulary through short, enjoyable repetition. Make cards with the term on one side and an explanation in the student's own words on the other. Review a few cards each day for a short time, since spaced repetition sticks far better than cramming in one night. Concept maps and term cards also make it easier to revisit older material when a new chapter calls on an earlier foundation.
Tips- Keep the concept map on the study wall so it is seen often
- Review five to ten cards per session, but do it regularly
- 6
Practice questions by type, then review on a schedule
The final step closes the learning loop. Work through questions that represent each type, from recognizing a concept, reading tables and graphs, to applying a concept to a new situation. Science literacy questions often present a story or data first, so students need to grow comfortable reading the context calmly before answering. Each time they get one wrong, trace where the mistake lies, whether in understanding the concept or in reading the question carefully. Schedule periodic reviews every few weeks so older material stays fresh. Focused practice helps students understand the patterns, so facing new questions feels calmer.
Tips- Group questions by type, not by page number
- Keep a log of mistakes so they do not repeat in the next exam
Integrated science map for grades 7 to 9
| Grade | Main focus | Example of cross-branch connection |
|---|---|---|
| Grade 7 | Measurement, matter and its states, heat and temperature, classification of living things, ecosystems | Heat affects the state of matter and life within an ecosystem |
| Grade 8 | Motion and force, pressure, human organ systems, vibration, sound, and light | Air pressure links physics with the work of the respiratory system |
| Grade 9 | Electricity, magnetism, heredity, biotechnology, and particles of matter | Electrical properties in nerve cells connect physics with body biology |
Topic order may differ between schools. Use this table as a picture of connections, then adjust to the book in use.
Weighing two ways to study science
- Material comes together into one whole, memorable story
- Students grow used to linking cause and effect across branches
- Suits science literacy questions that demand holistic reasoning
- The grade 7 foundation is reused in grades 8 and 9
- Each chapter feels standalone without a clear connection
- Terms are easily mixed up with no binding theme
- Students struggle when a question combines several branches at once
- Older material fades quickly once a new chapter begins
“A child who understands integrated science learns to see water, light, and the body as one web of phenomena. Once they master a single theme, the branches of science around it open on their own.”
